SEBI Tightens F&O Rules to Curb Speculation and Protect Investors

In a significant move to enhance the safety and fairness of India's equity derivatives market, the Securities and Exchange Board of India (SEBI) is introducing a new set of reforms for Futures and Options (F&O) trading. These changes are aimed at reducing risky speculation, enhancing risk checks, and protecting retail investors from significant losses. The rollout begins on July 1 and is scheduled to conclude by December 6, 2025.

What's Changing? Here's a Quick Breakdown:

1. Tighter Position Limits Based on Market Liquidity

SEBI is now linking the size of positions that can be taken in index derivatives to the liquidity of the cash market. In simple terms, the more active the underlying market, the more room you get to trade. This helps stop market manipulation and overly risky bets.

2. Smarter Risk Tracking Using 'Delta'

They're switching to a method called 'Future Equivalent' or Delta to measure risk. It sounds technical, but here's the gist: it gives a clearer picture of how sensitive your options positions are to market movements. By weighing your long and short positions, it calculates net exposure more accurately.

3. Higher Trading Limits (With a Catch)

Thanks to feedback from traders, SEBI has relaxed some of the proposed limits. Now, traders can hold gross option positions of up to ₹100 billion (up from ₹15 billion) and net positions of up to ₹15 billion (previously ₹5 billion). This is meant to allow serious trading without tipping into chaos.

4. Intraday Position Checks

To spot issues as they happen, exchanges will need to check positions at least four times a day. This is especially important on expiry days when trading tends to spike.

5. No More Expiry Day Spreads

Starting February 1, 2025, traders were unable to offset positions across different contract months (known as calendar spreads) on expiration days. Why? Because it's riskier and leads to high-volume spikes that SEBI wants to avoid.

6. Upfront Premiums for Options

Also from February 1, brokers were required to collect option premiums right when you place the trade, not at day's end. This reduces the risk of underfunded trades and ensures that traders have a sufficient stake in the game.

7. Bigger Minimum Contract Sizes

To raise the bar for entry, SEBI is increasing the minimum contract value from ₹5 lakh to ₹ 10 lakh to ₹15 lakh. Eventually, contracts will range between ₹15 and ₹20 lakh. This change encourages more responsible trading.

8. Fewer Weekly Expiries

Currently, there are too many weekly expiry contracts circulating. SEBI trimmed it down to just one weekly expiry per index, per exchange. Starting November 20, 2024, traders saw only six weekly contracts each month instead of 18.

Why All These Changes?

It's no secret that retail trading in futures and options (F&O) has exploded. However, here's the catch: a SEBI study found that over 93% of retail traders lost money, amounting to ₹1.8 trillion, over three years. That's a wake-up call.

These reforms aim to address this issue by tightening controls, making risk easier to track, and raising the entry barrier just enough to prevent casual, high-risk bets. It's all about creating a safer space for investors without choking market activity.

Who's Affected and How?

Retail Traders: If you're a small investor, these rules might make F&O trading feel less accessible. Bigger contract sizes and upfront premiums mean you'll need more capital to participate.

Institutional Investors: Better risk tracking and updated position limits help institutions manage exposure more precisely, which is good news for risk managers and fund strategists.

Brokers & Exchanges: These entities will need to upgrade their systems to handle more frequent monitoring and new rules surrounding expiry days. It's more work, but it's meant to boost market trust.

When Do These Changes Kick In?

Here's SEBI's timeline:

• November 20, 2024: Weekly expiries are cut, and contract sizes are raised.
• February 1, 2025: Upfront premiums + end-of-expiry-day spreads.
• April 1, 2025: Intraday position monitoring begins.
• July 1–December 6, 2025: Full rollout of all reforms, including new limits and risk methods.

Final Thoughts

SEBI's overhaul of F&O trading rules isn't just about patching holes; it's a proactive push to future-proof the market. With more people trading derivatives than ever before, the goal is to maintain stability, fairness, and a lower level of risk, especially for everyday investors.

If you're in the market, now's the time to review your strategies, update your risk systems, and prepare for a new era of trading.
